entmake创建图元较command速度快,且不受捕捉等CAD环境因素影响,因此优先选用entmake。

entmake创建图元必要条件,即创建图元的最少组码项,再少就无法正确创建图元,实际使用中需要颜色、图层等组码项自己添加。水平有限,欢迎拍砖。

1、直线

(entmake (list '(0 . "LINE") (cons 10 pt1) (cons 11 pt2)))

2、两顶点多段线(多顶点类似)

(entmake (list '(0 . "LWPOLYLINE") '(100 . "AcDbEntity") '(100 . "AcDbPolyline") (cons 90 2) (cons 10 pt1) (cons 10 pt2)))

3、点表生成多段线

(entmake (append (list '(0 . "LWPOLYLINE") '(100 . "AcDbEntity") '(100 . "AcDbPolyline") (cons 90 (length lst))) (mapcar '(lambda (pt)(cons 10 pt)) lst ))

)

4、圆

(entmake (list '(0 . "CIRCLE") (cons 10 pt) (cons 40 r)))

5、圆弧

(entmake (list '(0 . "ARC") (cons 10 pt) (cons 40 r) (cons 50 ang1) (cons 51 ang2)))

6、单行文本

(entmake (list '(0 . "TEXT") (cons 1 str) (cons 10 pt) (cons 40 5)))

7、多行文本

(entmake (list '(0 . "MTEXT") '(100 . "AcDbEntity") '(100 . "AcDbMText") '(7 . "Standard") (cons 1 str) (cons 10 pt)))

8、半径标注

(entmake (list '(0 . "DIMENSION") '(100 . "AcDbEntity") '(100 . "AcDbDimension")(cons 10 pt) '(70 . 36) '(100 . "AcDbRadialDimension") (cons 15 pt1) ) )

9、直径标注

(entmake (list '(0 . "DIMENSION") '(100 . "AcDbEntity") '(100 . "AcDbDimension") (cons 10 pt1) (cons 11 pt2) '(70 . 163) ' (100 . "AcDbDiametricDimension") (cons 15 pt3)

)

)

10、水平标注

(entmake (list '(0 . "DIMENSION") '(100 . "AcDbEntity") '(100 . "AcDbDimension") (cons 10 pt) '(70 . 32) '(1 . "") '(100 . "AcDbAlignedDimension")

(cons 13 pt1) (cons 14 pt2) '(100 . "AcDbRotatedDimension")

)

)

11、垂直标注

(entmake (list '(0 . "DIMENSION") '(100 . "AcDbEntity") '(100 . "AcDbDimension") (cons 10 pt) '(70 . 32) '(1 . "") '(100 . "AcDbAlignedDimension")

(cons 13 pt1) (cons 14 pt2) '(50 . 1.5708) '(100 . "AcDbRotatedDimension")

)

)

12、倾斜标注

(entmake (list '(0 . "DIMENSION") '(100 . "AcDbEntity") '(100 . "AcDbDimension") (cons 10 pt1) '(70 . 33) '(1 . "") '(100 . "AcDbAlignedDimension")

(cons 13 pt2) (cons 14 pt3)

)

)

13、entmake生成普通块

(defun emkblk (ss pt name / i)

(entmake (list '(0 . "block") (cons 2 name) '(70 . 0) (cons 10 pt)))

(repeat (setq i (sslength ss)) (entmake (cdr (entget (ssname ss (setq i (1- i)))))) )

(entmake '((0 . "ENDBLK")))

(command "_.erase" ss "")

(entmake (list '(0 . "INSERT") (cons 2 name) (cons 10 pt)))

)

14、entmake插入普通块

(entmake (list '(0 . "INSERT") (cons 2 name) (cons 10 pt)))

15 、entmake生成无名块

(defun emkunameblk (ss pt / i name)

(entmake (list '(0 . "block") '(2 . "*U") '(70 . 1) (cons 10 pt)))

(repeat (setq i (sslength ss)) (entmake (cdr (entget (ssname ss (setq i (1- i)))))) )

(setq name (entmake '((0 . "ENDBLK"))))

(command "_.erase" ss "")

(entmake (list '(0 . "INSERT") (cons 2 name) (cons 10 pt)))

name

)

16、将选择集做成属性块(选择集中单行文本作为属性)

(defun emkattblk (ss pt name / ent i)

(entmake (list '(0 . "block") (cons 2 name) '(70 . 2) (cons 10 pt)))

(repeat (setq i (sslength ss))

(setq ent (entget (ssname ss (setq i (1- i)))))

(if (= (cdr (assoc 0 ent)) "TEXT")
